Abstract

A method for flexible and secure transmission of digital content to an end user device comprises the steps of: (a) providing a control center (240) for controlling access to the digital content by the end user device (310); (b) transmitting scrambled digital content to a first end user device (310) by a second end user device (310), such that said second end user device cannot play back said scrambled digital content; (c) connecting said second end user device (310) to said control center (240); and (d) transmitting a permission message to said second end user device (310) by said control center (240), such that said second end user device is able to unscramble said scrambled digital content to form unscrambled digital content.
